The correct answer is D. granting former slaves suffrage.
Step-by-step explanation:
From the question, the main amendment was not specified. However, from my research, it deals with the 15th amendment.
The 15th amendment of the United States Constitution centers on the need to improve the voting rights of blacks in America, especially the rights of slaves to cast their votes. The 15th amendment was passed into law 1869 and was later approved in 1870.
Basically, from the wordings of the amendment, it ensured blacks were free from discrimination and segregation in all forms.
